I have a 720 but I suspect it will be the same or similar. Tap the screen and then Change Preferences. Use the forward arrow to scroll to the relevant page (5 on mine) where you will find Set Units. Tap this and then change whatever units you wish.
Hi Juanin, just posted this for a near identical problem with a Tomtom 700;
When you get this kind of problem with a Tomtom device always start with the memory card, so:
1: remove the card, clean the contacts and if you have an air duster (available from any good hardware store/electronics store) clean the card slot, then reinsert it.
2: make sure the card is readable on your PC to ensure it doesn't have a problem. if this doesn't help then
3: format the card and reinstall the maps & software on to it.
4: make sure the card is reinserted correctly.
Next is the battery, leave the device switched on until the battery runs out, switch it on again and it should stay on for a moment then switch its self back off, repeat this until it will not switch on anymore and then charge it for at-least 16 hours before trying it again, this will re-calibrate the battery.
Diagnosing a problem is a process and this is just the start of it, don't be disheartened if this doesn't help, just message back with the results.
